Whenever I re-barrel my 270 WSM I will go with a 1 in 7 or 1-8 because of more new longer bullets. Not sure if the Weatherbys speed will make up for a slower twist or not with the 170s and other VLDs. Hill Country Rifles thought the 1-8 was on the fast side for the 6.5x300 Weatherby and build theirs with 1 in 9 twists. At least for them it has proved more accurate. The only light weights I will shoot are the mono metals so the higher RPM could increase the leathality or so some believe.
Which barrel makers twist 270 cal faster than 1-9? Most are 1-10 only.
"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
